IMO the editor client method should be named similarly to the setting (shouldEchoPassword or something)

> Source/WebKit/UIProcess/ios/WKContentView.mm:172

I’m not sure it makes sense to mirror the main screen’s state, we should send the message (with the right window’s state) when we’re parented instead.

Should always be using the WebView or content view screen

[Tim Horton]

Also, nothing is pushing the right state in the process swap or crash case. You should add a bit to WebPageCreationParameters that, if parented, provides the current window’s state.

Nit - `suppressPasswordEcho`.

Nit - `suppressPasswordEcho`.

Nit - space before the *.

I think you meant to delete this.

Oh also — is UIScreenCapturedDidChangeNotification dispatched when we’re unparented or parented? (e.g. what happens if the screen is being captured in a WKWebView, but then the web view is removed from the view hierarchy and added later after screen capture has ended?)

shouldSuppressPasswordEcho

setScreenIsBeingCaptured.

> +void WebPageProxy::setIsScreenCaptured(bool screenMirroring)

The dissonance between "captured" and "mirroring" is confusing.

> Source/WebKit/WebProcess/WebCoreSupport/ios/WebEditorClientIOS.mm:122

shouldSurpressPasswordEcho

> Source/WebKit/WebProcess/WebPage/WebPage.h:670
> +    bool isScreenCaptured() const { return m_isScreenCaptured; }
> +    void setIsScreenCaptured(bool);

isScreenBeingCaptured?

> Source/WebKit/WebProcess/WebPage/ios/WebPageIOS.mm:4281
> +void WebPage::setIsScreenCaptured(bool captured)

I would say "being captured" here. We're not capturing the screen, someone else is. "captured" is also vague here (easily confused with pointer capture). Can we say "being mirrored" instead?

> Source/WebKitLegacy/ios/WebView/WebUIKitDelegate.h:131
> +- (BOOL)surpressPasswordEcho;

Sounds like a verb. Should be isPasswordEchoSurpressed.

> Source/WebKitLegacy/mac/WebCoreSupport/WebEditorClient.mm:833
> +bool WebEditorClient::surpressPasswordEcho() const

isPasswordEchoSurpressed

> Source/WebKitLegacy/mac/WebView/WebViewData.h:248
> +    BOOL surpressPasswordEcho;

isPasswordEchoSurpressed?

Missing a "being" here.

I think this should be added to the passwordEchoEnabled expression, rather than put in a separate boolean.

> Source/WebKitLegacy/mac/WebView/WebView.mm:1528
> +    if ([[self _UIKitDelegateForwarder] respondsToSelector:@selector(shouldSuppressPasswordEcho)])

I think this code should be removed.

> Source/WebKitLegacy/mac/WebView/WebViewData.h:248
> +    BOOL shouldSuppressPasswordEcho;

I think this should be removed. It’s set but never read.
